Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and specifically to a pusher cooling structure for injection molding equipment. Background Technology

[0002] After injection molding, the product adheres tightly to the mold core or insert. The ejector block of the injection molding machine pushes the product out of the mold, allowing it to detach smoothly. Therefore, water is needed to cool the ejector block, enabling the product to be ejected from the mold more quickly. Existing ejector blocks use soft rubber tubing connected to external water pipes. However, soft rubber tubing is relatively soft and has poor shape retention. When the ejector block moves, the soft rubber tubing can interfere with other parts, making it easily crushed. Utility Model Content

[0003] To address the problem that the flexible rubber hose used to connect water flow in the push block of existing injection molding machines is easily crushed, this application provides a cooling structure for the push block of an injection molding machine. The specific technical solution of this application is as follows:

[0004] A cooling structure for a pusher block in an injection molding machine includes: a base plate, an insert, a pusher block, a push rod, and a water channel connecting block. The insert is fixedly mounted on the base plate. The push rod passes through the base plate and the insert in sequence and is fixedly connected to the pusher block, allowing the pusher block to be movably mounted above the insert. A guide groove is provided on the side of the insert. The water channel connecting block is movably mounted in the guide groove. The upper end of the water channel connecting block is fixedly connected to the pusher block, and the lower end is connected to an external water pipe. A water flow connection channel is provided in the water channel connecting block for inputting and outputting water flow to the pusher block.

[0005] Furthermore, the bottom of the push block is provided with a mounting seat for mounting the push rod, and the top of the insert is provided with a placement groove for placing the mounting seat.

[0006] Furthermore, the side of the mounting base and the side of the upper end of the push rod are provided with first screw holes.

[0007] Furthermore, the top of the insert is provided with a protrusion, and the pusher is provided with a through hole that mates with the protrusion.

[0008] Furthermore, a fixing block is provided at the bottom of the insert, and a groove for placing the fixing block is provided on the base plate, with the push rod disposed in the groove.

[0009] Furthermore, the side of the push block is provided with an installation groove, the installation groove is provided with an outlet and an inlet, and the upper end of the water circuit connecting block is provided with a bend, the bend being fixedly installed in the installation groove.

[0010] Furthermore, the lower end of the water circuit connecting block is provided with two water nozzles that are connected to external water pipes. The water nozzles are respectively connected to the outlet and inlet of the push block through the water circuit connecting block.

[0011] Furthermore, a second screw hole is provided in the bent portion and the mounting groove.

[0012] Furthermore, the top of the push block is provided with a plurality of striped grooves arranged in a row.

[0013] Compared with existing technologies, the beneficial effects of this application are as follows: The push block cooling structure of the injection molding equipment described in this application replaces the soft rubber tube used by the push block for connecting with external water flow with a water channel connecting block. The water channel connecting block has better shape. When the push block is pushed out and returned under the action of the push rod, the water channel connecting block moves along the guide groove of the insert in the same way, without contacting other parts, thus reducing the risk of damage to the water channel connecting block.

[0024] like Figures 1 to 4 As shown, this invention relates to a pusher block cooling structure for injection molding equipment, aiming to improve the cooling efficiency of the pusher block 4 during injection molding, ensure molding quality, and extend the service life of the equipment. The specific technical solution is as follows:

[0025] The cooling structure of the ejector block 4 in the injection molding equipment includes a base plate 1, an insert 2, an ejector block 4, an ejector rod 5, and a water channel connecting block 6. The water channel connecting block 6 is made of a hard material, such as plastic, stainless steel, or copper. The insert 2 is fixedly mounted on the base plate 1, providing stable support for the entire structure. The ejector rod 5 passes through the base plate 1 and the insert 2 sequentially and is fixedly connected to the ejector block 4, allowing the ejector block 4 to move above the insert 2 to eject the injection-molded product 3 after injection molding. A guide groove 7 is provided on the side of the insert 2 to guide the installation and movement of the water channel connecting block 6. The water channel connecting block 6 is movably mounted in the guide groove 7, with its upper end fixedly connected to the ejector block 4, allowing it to follow the ejector block 4 in ejection and return movements. Its lower end is connected to an external water pipe. The water channel connecting block 6 has a water flow channel for providing cooling water to the ejector block 4 and guiding hot water from the ejector block 4 out, thereby effectively reducing the temperature of the ejector block 4 during the injection molding process and improving cooling efficiency.

[0026] In one embodiment, the bottom of the push block 4 is provided with a mounting seat 8 for mounting the push rod 5, and the top of the insert 2 is provided with a placement groove 9 for placing the mounting seat 8. This design not only improves the connection stability between the push block 4 and the push rod 5, but also optimizes the compactness of the overall structure.

[0027] In one embodiment, the side of the mounting base 8 and the side of the upper end of the push rod 5 are provided with first screw holes 10, and the upper end of the push rod 5 is fixed to the mounting base 8 by screws, which further enhances the connection strength between the push block 4 and the push rod 5.

[0028] In one embodiment, the insert 2 has a protrusion 11 on its top, and the push block 4 has a through hole 12 that mates with the protrusion 11. This design allows the push block 4 to be precisely installed on the insert 2, ensuring the stability of the push block 4 during movement.

[0029] In one embodiment, a fixing block 13 is provided at the bottom of the insert 2, and a groove 14 for placing the fixing block 13 is provided on the substrate 1, with the push rod 5 disposed in the groove 14. This structural design not only improves the connection stability between the insert 2 and the substrate 1, but also provides stable support for the push rod 5.

[0030] In one embodiment, the push block 4 has a mounting groove 15 on its side, with an outlet 16 and an inlet 17 in the groove. The upper end of the water connection block 6 has a bend 18, one end of which is fixedly positioned in the mounting groove 15. This design allows the water connection block 6 to be securely mounted on the push block 4, ensuring smooth water input and output.

[0031] In one embodiment, the lower end of the water connection block 6 is provided with two water nozzles 19 that connect to external water pipes. The water nozzles 19 are connected to the outlet 16 and inlet 17 of the push block 4 through the water connection block 6, respectively. This design ensures that the push block 4 has a circulating water supply, thereby improving the cooling effect of the push block 4.

[0032] In one embodiment, the bending portion 18 and the mounting groove 15 are provided with a second screw hole 20, which is fixed by screws, further enhancing the connection stability between the water channel connecting block 6 and the push block 4.

[0033] As one embodiment, the top of the push block 4 is provided with a plurality of striped grooves 21 arranged in a row. This design not only improves the cooling effect of the push block 4 on the injection molded product 3, but also plays an auxiliary role in the molding process.

[0034] The cooling structure of the ejector block 4 of the injection molding equipment described in this application uses a water channel connecting block 6 instead of the soft rubber tube used for connecting the ejector block 4 to the external water flow. The water channel connecting block 6 has better shape. When the ejector block 4 is pushed out and returned to its original position under the action of the push rod 5, the water channel connecting block 6 moves along the guide groove 7 of the insert 2 in the same way, without contacting other parts, thus reducing the risk of damage to the water channel connecting block 6.

[0035] In summary, this invention provides a pusher block cooling structure for injection molding equipment through innovative structural design and an efficient cooling system. This structure can significantly improve cooling efficiency, optimize equipment performance, and extend service life, demonstrating significant technological advancement and practical value.
